I have the P0455 code and I have a quick ?, when I get the code I can feel the truck bog down under load but it's not constant, it comes and goes. So I clears the code and then I can drive for days even weeks without the code then out of the blue it will come back. Sometimes when it comes I can shut the truck off and start it right back up and the truck drives good as new, what could cause this?
